Each instant messaging platform of sorts offers its own appeal. Snapchat's appears to be the ability to share moments of spontaneity that won't linger around for the rest of your life. Pictures and clips disappear after they're viewed. Unless, that is, you Replay them. This is a feature that has been around for a couple of years now, but users have been limited to one per day.

Now Snapchat is providing the option to replay things more often. However, this feature doesn't come free. Snapchatters have to buy Replays, starting at a three for 99 cents. Even then, each Snap is only eligible for one Replay.

Primer by Google (formerly listed in the Play Store as Primer: Marketing for Startups) is a simple little Android app that helps small business owners get their company off the ground and in the public eye. Users view a number of brief, bite-sized lessons and walk away with a general understanding of what they need to do. That's the idea, anyway.

The Motorola Connect app isn't required to use a Moto 360, but it's what you need to install in order to tweak some of the device's default watch faces.

The latest update adds four more to the list, along with the ability to change the color of the smartwatch's charging screen from the default blue. There are five to choose from altogether: blue, red, green, purple, and yellow.

The SMS app that comes with new phones tends to suck in one way or another. Why is the interface so ugly? Bah, switching between conversations is so awkward. Samsung, what are you doing? Motorola, the old Messaging app no longer feels stock―it just feels old.

When you ask a friend for good alternatives, don't be surprised if you hear them mention EvolveSMS. Not only is the app pretty, the combination of using the side panel to list conversations and swiping left or right to switch between them is just plain convenient.

Now version 4.0 is here. Unfortunately, you're not going to get to enjoy most new features just yet without the right hardware.

Periscrope is Twitter's app for broadcasting live streams. Something's happening. You pull out your phone, you turn on the camera, and you show the world what's going on. Or at least the people who come across your account.

Since launch, the app has only supported vertical videos. But enough people have scoffed at this idea that the team is now introducing the option to turn your phone sideways. Landscape recording is making its way into the latest Android and iOS versions of the app.

Other additions include showing a list of mutual followers to pick from when you start a private video stream.

Google's new editor borrows from Search and Maps, where details pop up on a card from the bottom of the screen. You now have the ability to not just designate specific hours of operation, but to show if you're open 24 hours.

YouTube Kids is like YouTube... but for kids. Okay, it's not the most difficult concept in the world. Neither is the urge to take a video streaming to your tablet and make it bigger. With the latest version of YouTube Kids, your little one now has that option. Chromecast support has arrived.

Minecraft Pocket Edition updates are often filled with minute changes that you have to be familiar with the game to understand. Version 0.12.1's changelog includes a number of these tweaks. For example, there's "Ocelots! Try taming one with a fish" and "Golems. We recommend you approach with caution." Also, "Sneaking and sprinting! Express yourself through movement!"

SmartThings users have the luxury of controlling a large number of things from a single spot—their phones. That means the app SmartThings relies on must be pretty good, or the entire experience falls to pieces. To coincide with the formal release of its second generation Hub (which went on pre-order last month), the company is now pushing out an update to its Android app.

The WordPress developers have bumped the Android app up to version 4.4, introducing a number of visual tweaks in the process. Some of them are better for phones than they are for tablets. Whether they're an improvement is for you to judge.

For starters, the page and post list page has changed from two panels into a list of floating titles. You can see the headline, a few lines of text, and a featured image. Edit, Preview, Stats, and Trash options line the bottom.

This change results in less information displayed on tablets in landscape mode than we saw in previous versions.
